As Nick asked, does the problem follow the UPS? I.e., if you swap which UPS is connected to which machine, do things stay the same? And if you only swap the cables but not the UPSs? If the problem follows the cable, then its the cable. If the problem follows the UPS, then the UPSs aren't really identical, and you should find out how they differ (settings, firmware version, hardware revision, etc). If not, then its the machines themselves. Assuming there really are no other relevant differences between dmesgs (BIOS versions, kernel versions), or kernels (e.g. something on /etc/bsd.re-config), I'd double check _all_ BIOS settings. > On Monday, December 1st, 2025 at 2:16 AM, Nick Holland > <[email protected]> wrote: > > > > > > > On 11/30/25 10:34 AM, otto.cooper wrote: > > > > > I thought I had good news, but I doubt it now. > > > > > > Two identical Supermicro attached to two identical UPS from EATON, using > > > the latest release of obsd, see the usb ups link randomly. > > > > > > I just disabled usb3 and xhci hand-off from their bios, leaving ehci on. > > > One machine now detects the ups, the other one does not. > > > > > > so...you do realize how many hundreds, maybe thousands of different > > SuperMicro systems have been made over the years?
